I've never done much surfing on my boat but just recently had a friend come in town who really wanted to surf. He had a Liquid Force Mega Wake Shaper that we used and it put out a pretty good wave with just the stock (1800 lbs) ballast, a full tank of gas and 5 people in the boat. I was thinking of picking one of them up so I could have the option to surf in the future but one thing I was thinking about while we were riding was the exhaust. How necessary is it to have an FAE / surf pipe?
